The working mechanism of tooth belts is based on the interaction between the belt's teeth and the pulley grooves. When the pulley rotates, the teeth of the belt mesh with those of the pulley, creating a mechanical link that transmits torque. This system allows for high torque transfer with minimal backlash, which is particularly advantageous in applications requiring precise positioning, such as in robotics or CNC machines. Additionally, tooth belts operate quietly compared to chain drives, making them suitable for environments where noise reduction is essential.

Most modern vehicles are equipped with a timing belt instead of a timing chain due to its quieter operation and lighter weight. However, timing belts are not meant to last indefinitely. Depending on the vehicle's make and model, these belts typically need to be replaced every 60,000 to 100,000 miles. Failing to replace a timing belt on schedule can lead to catastrophic engine damage, including bent valves and a complete engine failure, which can be incredibly costly to repair.
